Is there anyone who knows the answers of these two long-standing questions?
1. How can the orbital electron rotate permanently without energy supply?While this is hardly an answer to the question, recall the revolution that Newton brought to understanding of motion at constant velocity over that achieved by Galileo.

2. How can the orbital electron keeps its position without merging into its nucleus when an external pressure applied on it if its kinetic energy balances delicately with its potential energy?

See the Wikipedia article for the Bohr model. http://en.wikipedia.org/wiki/Bohr_model Electrons are waves and have quantized energy levels.
